Open-source InVideo alternatives

DramaClaw is a general-purpose AIGC video engine that moves from script to finished film in a single pipeline. It is used for short dramas, advertisements, product videos, otome games and more, and its team says it is the same production line they use internally, covering storyboards, assets, voice synthesis and video generation. Topics include text-to-video, image-to-video, TTS and AI filmmaking.

The software is written in Python with FastAPI and a React front end and is self-hosted. Documentation, a quick start and trailers are provided, with README versions in several languages. Sample short dramas produced with the pipeline are linked from the repository.

Licensing is notable: DramaClaw uses the Elastic License 2.0, so it is source-available rather than open source. The standalone version is free for commercial use without asking permission, on the condition that a small Powered by DramaClaw credit appears in the interface, but wrapping it as a hosted SaaS for other people is not allowed under the current license. The repository was created in March 2026, so the project is young.

Short Video Factory is an open-source desktop application that simplifies short video production with AI. You supply a text prompt together with storyboard footage, and the app generates copy, voiceover, edits and subtitles to produce marketing and general-interest clips with little manual work.

According to its README, the toolchain covers AI-driven script writing from prompts, text-to-speech narration, automated clip editing across common video formats, automatic subtitles and visual effects, and batch processing so multiple tasks can run in sequence from presets. It is a cross-platform desktop program for Windows, macOS and Linux, aimed at an out-of-the-box experience, and its topics reference TikTok-style short video content.

The project is written in TypeScript and licensed under AGPL-3.0. Its documentation is mainly in Chinese, with an English summary in the repository tagline. It suits marketers, small businesses and content creators who need to produce many short product or promotional videos quickly on their own computer.

ArcReel is an open-source video production workspace that you host yourself. Its AI agents convert novels, finished scripts or product material into characters, scenes and props, then storyboards and video, aiming for shots where characters stay consistent and the process remains controllable and editable.

The workflow outputs finished clips and can produce draft projects for the CapCut editing app, called JianYing in China, for further editing. The README highlights consistency across shots, support for multiple model providers, and cost tracking so you can see what each generation costs. Repository topics mention the Claude Agent SDK, FFmpeg, image-to-video and text-to-video generation, short drama and storyboarding. It is built in Python and deployed with Docker.

ArcReel is licensed under AGPL-3.0, with documentation mainly in Chinese. It suits short-drama creators, small studios and marketers who want an AI video pipeline on their own server using their own model API accounts.

ShortGPT is an experimental AI framework for automating the creation of short-form video content such as YouTube Shorts and TikTok clips. It is aimed at creators who want to reduce the manual work of scripting, footage sourcing, voiceover synthesis, captioning and editing for high-volume short video channels.

It provides an LLM-oriented video editing language with ready-to-use scripts and prompts, voiceover generation in more than 30 languages through EdgeTTS, automated caption generation, and sourcing of images and video assets. The project showcases voice dubbing and automated editing workflows in demo videos, and it is primarily run as a local web app, with Google Colab recommended for an easier setup.

ShortGPT is written in Python, uses GPT-4 and other OpenAI capabilities, and is released under the MIT license. It is described as experimental, so users should expect ongoing changes and review the installation notes before running it, and API usage with providers such as OpenAI is billed separately.
